Objective – To investigate the antimicrobial activity of nanoparticles against phytopathogenic bacteria and phytoplasmas. To determine the optimal nanoparticle doses under controlled and field conditions. Methods – microbiological, phytopathological, biochemical, biotechnological, molecular genetic, and statistical. Studies of the antibacterial activity of nanopreparations have shown varying levels of effectiveness of carboxylates from biomaterials against phytopathogenic bacteria. The highest bactericidal effect was observed for nanoparticles of Ag, Cu, Co, Se, Bi, as well as I₂ and Sn against Pectobacterium carotovorum, Pseudomonas syringae pv. syringae, P. fluorescens, Xanthomonas campestris pv. campestris, Clavibacter michiganensis, and Agrobacterium tumefaciens, while Ni, Ce, and V showed lower activity. For copper-containing preparations against pathogens of walnut bacteriosis, CuSO₄ and CuO + Cu(OH)₂ were the most effective, while Agrobacterium spp. showed increased resistance; the use of antibiotics Kasugamycin and Zhongshengmycin requires clarification of the norms of use in the protection system. Pre-treatment of wheat seeds in 0.3%Co nanocitrates had a positive effect on germination. The effects of I₀․₅ and Co₀․₃ on photosynthetic indicators, rhizosphere microbiome, and productivity were variety-specific and depended on the previous temperature stress and the type of phytopathogen. In general, I₀․₅ was the most effective for increasing yield ( Zymoyarka +24%, Zelma +15%, with an increase in 1000-grain weight), while Co₀․₃ provided a moderate effect mainly in the Zelma (6%) and only a trend in the Zymoyarka, which confirms the need for differentiated use of nanocitrates depending on the variety and stress conditions.
